Actually , there are two discrepancies in the airbus manuals , and one of them was never mencioned in the final report.
In the FCOM 3.01 -Limitations , it states that the max.demonstrated xwind is 38Kts. Gusts included. This is the value mentioned in the report.
I think you will find that this is an amendment, subsequent to and almost certainly because of the Hamburg incident, which occurred two years ago when the other figures applied.
